SPECIFICATION forming part 0f Letters Patent No. 478,224, dated July 5,1892. Application tiled March 5, 1892. Serial No. 423.945. (No model.)

To all whom, it may concern; Y

Be it known that we, FRANCIS JOHN COL and GEORGE BLAGDEN HAzLEHURs'r,citizens` of the United States, and residents of the city of Baltimore,State of Maryland, haveinvent-v ed certain new and useful Improvementsin tion through the oil-cup. Fig. 2 is a plan of the exterior of theoil-cup. Fig. 3 is an elevation of the adjustable cap for regulating thefeed. Fig. 4 is a plan of the same.V Fig. 5 is an elevation of thecentral shan k or valvecase with the oil-inletlshown in full. Fig. 6 isa side elevation of the saine turned at an angle of ninety degrees withthe previous position. Fig. 7 is a plan of the same.

A is a cup arranged to contain oil.

B is a cap or cover screwed into the top of the cup.

D is an independent stein or shank containing the spindle and providedon its end with a screw-thread for fastening the cup on the part towhich it is to be attached, and having a thread on its upper end uponwhich is screwed the adjustable cap for regulating the feed.

E is a channelfway or hole cut through the center of said stemtransversely and of a size larger than the valve-stein on the interiorof the shank.

F is a hole through the center of the stein D of smaller size below thetransverse hole E than above it, andhaving a valve seated upon its upperend at the point where it cnters the hole E from below.

G is a valve-stem or vibrating spindle which forms a valve at its lowerend. The lower portion is smaller than the upper part and enters thehole F, which is below the oil-inlet E, while its upper portion islarger and about fills the larger hole in the upper portion of sition ofthe cap and its yoke.

seat. -it will be impossible to remove the oil-cup cap J, which iscylindrical at its lower por- Y tion, open at the top, and having a yokeK across the top connecting the two sides. This cap' may of course bemade of any other shape so long as it has an internal screw. This yokeis quite high, so as to stand considerably above the cylindrical portionof the cap. The top of the valve stem or rod Grests or stands just belowthe under side of the yoke K, and the amount'of motion permitted to thevalve-stem is dependent upon the po- The cylindrical portion of the capJ is split on one side at the pointmarked L. This slit is somewhat open,so that by pinching the cylindrical portion of the cap'it may be made toit tightly uponthe thread I-I, and be made to retain its position whilethe machinery is in operation.

The operation of the device is as follows: Vhen the oil-cup is to beattached to a piece of machinery-such as a locomotive, for instance-theoil-cup is put on and the spindle screwed through its bottom into thehole provided for it. A specially-constructed wrench having a deepsocket is then placed over the shank and it is screwed down firmly ontoits When this is done, it will be seen that without taking it apart andalso without this special wrench to take hold of the stem. Thisdifficulty avoids the loss of these oilcups by theft, which frequentlyhappens in the forms which can be easily removed with the ordinarywrench. The spindle or valvelstem is then placed in the center of thestern with its shoulder bearing upon the Valve-stein.. The cap is thenscrewed on, the threads fitting tightly upon the thread H on the upperend of the stem D, so asto hold it'rigidly in any position at which itmay be placed. It should be so adjusted that a small amount of play,from one thirty-second to one-sixteenth of an inch, be left between thetop of the spindle IOO and the under side of the yoke, so as to permitany desired amount of play in the valvespindle. The cup is then filledwith oil and the cap screwed in place. W'hen the niachinery is in rotarymotion the rapid up-and down motion of the crank will canse a similarthrow of the spindle and permit oil to flow through the transversechannel-way E, through the valve and the inlet-opening F to the bearing.The feed of the spindle may be easily adjusted by a simple turn or partturn of the adjustable cap and the amount of feed of the spindle can beseen at a glance upon taking off the top of the oilcup. The transversehole E, being at the bottom of t-he cup instead of the top, as is usualin many cases, permits the oil-cup to be drained to the very bottom.

In most oil-cups heretofore made the cup and stem by which it is screwedto the machinery are cast in one piece and are both made of brass. Tehave found it to be of advantage 1o make the cup of brass; but theinterior stem, by which the cup is held in place and through which theoil is fed to the hearing, we make of wrought-iron or steel. Thisgreatly strengthens the mechanism and mak es it difficult to knock itoff or remove it. The cap of my oilcup is solid and has no apertures init. It is screwed tightly upon the cup and prevents the escape of oil.This is `an advantage over other cups which have parts oi' the mechanismprotruding through the top of the cup for adjustment of the feed. Havingthus described our invention, what we claim, and desire to secure byLetters Patent isl The combination of an oil-cup with an independentcentral stem passing through the oil-cup and whereby it is secured tothe machine to be lubricated, having a hole through its center, withinwhich is a vibrating valve for controlling the flow of oil to thebearing, an adjustable cap consisting of a cylindrical portion which isscrewed upon the top of the central stem, and a yoke passing from oneside to the other across the top of the valvesteln, whereby the throw ofsaid stem is limited.

2. The combination of an oil-cup with an independent central stempassing through the oil-cup and whereby it is secured to the machine tobe lubricated, having a hole through its center, within which is avibrating valve for controlling `the flow of oil to the bearing, anadjustable cap consisting of a cylindrical portion which is split at onepoint, so as to be tightened or expanded by pressure, and a yoke passingacross the top from side to side, the under side of the interior ofwhich is in proximity to the top of the valve-stem,where by the throw ofthe valve-stem is limited.
